Yes. If you can, make a bootable clone as well.

  • I have a 2011 MacBook Pro and installed Mountain Lion recently and I want to uninstall it to my old software how do I do that?

    Please help me out I really don't like the Mountain Lion software, the old one i had was much better and I can't seem to figure out how to get back to the one I use to have.

    if you plan on doing an internet recovery install of your old os which is Lion - keep in mind that everything will be erased in your hard drive.  your files are gone - unless you have made copies of them in another drive.
    you will have to reinstall everything over again.  if you're prepared to do that, then click on the link below to learn on how to start internet recovery since booting through your recovery partition will reinstall Mountaln Lion.
    Force Lion to Start Internet Recovery.
    Now, if you have a early 2011 Macbook Pro - then it came with Snow Leopard - use your install disk to reinstall.

    Terribly sorry Joseph Kriz. I had absolutley no intention of annoying anyone. This was the first time I have been communicating in a discussion group, and as I wrote my comments I had no idea how my typing would reflect and where my question would be going. Hope my unintentional typing will be forgiven and causes no further agitation.The only additional comment I can make on your response is that "I do not use capital letters or CAPS LOCK while I try to enter my administrator password". Thank you for guiding me

  • USB-3 card reader that is compatible with MacBook Pro (Retina) and Mountain Lion

    Can anybody recommend a USB-3 based CompactFlash memory card reader that works with the MacBook Pro (Retina) and Mountain Lion (or, at least, Lion)?
    Thanks in advance...

    Thanks for your reply, Clinton. But I already have two readers that are USB-2 compatible. Now I need the one like I described above. I am using only the fastest CF cards available.
    I have read some user reports (on Amazon) on two readers relevant to my needs - SanDisk and Lexar - but I'm still not sure whether they are fully compatible with the Retina MacBook and Mountain Lion. As a matter of fact, I doubt it...

    I am thinking of upgrading my Macbook pro software to Mountain lion, and I just wanted to know if the airplay function is really all its cracked up to be?
    For example can I stream videos from VLC to my apple tv?
    Thanks team!!

    Your question asked.....
    Can either of these three connect to the existing router (which is not an Apple router and cannot be changed) wireless?
    So we understood that you wanted to connect to the existing router using wireless.
    If you can run an Ethernet cable from one of the LAN <-> ports on your existing router to the other house, then you could connect one of the Apple routers that way.
    Compare the Apple routers here to find one that might meet your requirements:

  • How long does it take to install mountain lion

    how long does it take to install mountain lion

    It depends on a number of factors - the speed of your computer and hard drive mostly. My experience has been that a standard upgrade will take 30-45 minutes. If you are erasing the hard drive and installing, it takes about 20-30 minutes, not counting migrating your data and applications.
    This doesn't count downloading which can take as litting as 40 minutes (a very fast broadband connection during off hours) to as much as several hours.

  • I have a MacBook Pro 2012 running Mountain Lion 10.7.5 and the mirroring icon isn't showing up to stream to Apple TV

    I have a MacBook Pro 2012 running Mountain Lion 10.7.5.  I've been trying to get the mirroring icon to show up in the bar but no dice.  Any tips?  I've gone into System Preferences -> Display and there is no option to turn on mirroring.

    Welcome to the Apple Community maricespieces.
    AirPlay Mirroring requires a second-generation Apple TV or later, OS X 10.8 or better and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). You can see which Mac you have and which operating system you are using by selecting 'About this Mac' from the Apple menu in the top left corner of your Mac and selecting the 'More Info' button.

  • TS3742 MacBook Pro 13" with Mountain Lion Freezing at login and getting Kernel errors

    Ive been working on a friends MacBook Pro 13" with mountain lion for about a week now. It is having intermittent kernal panic errors on boot up only. It is also freezing up frequently at apple logo. Disk check passed, reformatted and reinstalled os. Switched out Ram. Still happening. Can anyone help.

    Linc Davis,
    I hope this is what you were requesting. I deleted out the UUID but as far as hang reports, wasn't sure what that would look like so I am sorry if that is included in this. Please let me know what you think.
    Thank you for your help in this.
